1, that allows users to comply with industry standards in power
entry requirement.
2. Connector for cold condition, with pin temperature 65 C max.
3. Nickel-plated brass pins and soldering terminals.
4. Screw-on mount from front or rear (with screw type-M3).
5. Power module incorporates an IEC connector, double fuse
holder, voltage selector, double-pole power switch, all-in-one
easy-to-install unit.
6. Double-fuse holder designed for two fuses, single fuse & dual
fuse capability are both available (all 5x20mm fuses).
7. Adapts to 110-120V or 220-240V input voltage simply by
reversing the voltage selector card.
8. Compact design and high volume production provide maximum
flexibility and significant savings in space and cost over
assembly of individual components.
9. All part numbers are UL, CSA and SEMKO approved.
10. SK-1027/SK-1028 with a variety of built-in filter are also
